Elemental Composition Analysers Based on the Tagged Neutron Method

Currently the tagged neutron method (TNM) is actively used to determine the elemental composition of various substances: sinter, coal, iron and phosphate ores. The tagged neutron method consists in irradiation of the substance under study by fast neutrons with an energy of 14 MeV and registration of the induced characteristic gamma radiation. Neutron tagging is carried out by an alpha detector built in a neutron generator. The results of operation of TNM analyser for determination of elemental composition of iron ore are discussed.
